1 claim. 1

This invention relates to a refrigerator or icebox and it is one object of the invention to provide a refrigerator with a door of such construction that when it is closed, sealed spaces will be provided between companion door members and thus eliminate the necessity for using heavily packed doors which are of such weight that they are hard to move.

Another object of the invention is to provide a refrigerator door including companion door members hingedly mounted and so connected with each other that when the outer door member is moved in an opening or closing direction, the inner door members will move with it 'and thus make it unnecessary to individually open and close the inner door members.

Another object of the invention is to so mount the companion door members that they will be held in predetermined spaced relation to each other so that when the door is closed air will be confined between the door members and provide dead air between the door members as an insulating means for the door.

Another object of the invention is to provide a door construction which is triple in construction and capable of being installed in ice-boxes or other refrigerators of a conventional construction.

The invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a top plan view of the door.

Figure 2 is a view looking at the inner face of the door.

Figure 3 is an end view of the door.

Figure 4 is a fragmentary view upon an enlarged scale showing the door in transverse section along the line 4-4 of Figure 2.

This improved door is for use in connection with ice-boxes or other refrigerators as a closure for a food compartment or an ice compartment. This door has an outer door member I, an inner door member 2, and an intermediate door member 3 in the present illustration, but it will be understood that as many intermediate door members 3 may be provided as desired. A portion of the ice-box or refrigerator is indicated in general by the numeral 4 and there has also been shown a door frame 5. The frame 5 will be of suitable size and not only provided with the frame member at one side shown in Figure 4, but also with an opposite frame member and a top and bottom. Strips 6, 'l and 8 are provided for engagement by the door members when closed and upon referring to Figure 4, it may be seen that the strip 6 is directly secured to the wall of the refrigerator, whereas strips 'I and 8 are secured to strips 9 and CTI I0. Hinges Il and I2 are provided in order to mount the door members for swinging movement to opened and closed position, the hinges II for the outer door member being large strap hinges, and the hinges I2 being smaller hinges of the type used upon screen doors. When the door members are closed, they t snugly in the door way of the refrigerator with their side portions to which the hinges are attached abutting the wall of the refrigerator and the strips -9 and I0. Along their lower edges, the door members carry strips I3 which may be formed of any suitable ymaterial of the type used for weather stripping in order to provide a sealed joint between the door members and the bottom I4 of the doorway. Similar strips may be provided along the free side edges of the door members if so desired. Any suitable material may be used for forming the door members, but they are preferably formed of plywood having an inner facing I5 of CeloteX and painted with ice-box paint. When the outer door member is grasped by its handle I6 and opened or closed, the inner door members 2 and 3 are to be moved with it. In order to do so and in addition maintain the door members in predetermined, spaced relation to each other, there have been provided bars or blocks l1 which eX- tend diagonally between the door members, as shown in Figure 1, and are connected with the door members by hinges I8. Ends of the blocks or bars I1 are cut diagonally so that when the doors are closed, they will be held in spaced, parallel relation to each other and since marginal edges of the door members have close contacting engagement with portions of the door frames, dead air spaces will be provided between the door members.

The fact that the door members are held in spaced relation to each other is important, since the dead air spaces formed thereby will serve as an insulation against heat and transmission of heat through the door to the interior of the refrigerator will be prevented. It should also be noted that since the door for the refrigerator merely consists of inner, outer and intermediate door members which are separate from each other but connected for simultaneous movement, the door will be of light weight and may be very easily opened and closed.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after conn sidering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and arrangement of details coming Within the field of invention claimed may be resorted to in actual practice, if desired.

Having thus described the invention, what is 5 claimed is:

In combination with a refrigerator including a doorway having a frame and vertically extending strips alongronevside thereofpav door;l structune 4 taneously toward opened and closed positions and bevelled ends on the spacing strips to engage confronting areas of the door members and limit movement of the door in one direction.
